zng-app-context 0.7.0

This crate is part of the zng project.

Cargo Features

This crate provides 3 feature flags, 1 enabled by default.

"multi_app"

Allows multiple app instances per-process.

This feature allows multiple apps, one app per thread at a time. The LocalContext tracks what app is currently running in each thread and app_local! statics switch to the value of each app depending on the current thread.

"debug_default"

Enable "multi_app" in debug builds.

Enabled by default.

"dyn_closure"

Box closures at opportune places, such as Var::map, reducing the number of monomorphised types.

This speeds-up compilation time at the cost of runtime.
